Perfect, thanks for the response Wrench and Money!

One last question for you Wrench,

I'm about to make the switch to run E85. DW 800cc injectors, DW65c Fuel Pump, and Flex Fuel Tune.
From what I can tell you've been running it in your RDX? Any issues you have encountered I need to be concerned about?

How has the Blouch Turbo upgrade been holding up? Looking at doing the upgrade as well.

CSmoney28

I heard about tuning issues that may have been fixed but I’m not sure about that yet...thinking about doing it soon too if those tuning problems got worked out.

Just resurrecting an old thread. Several more Blouch upgraded turbos in circulation. Only one known failure and it was covered under warranty.

CSmoney28

What’s the price on it again?

Mr Hammond

Just passed 7,000 miles on mine. Absolutely love the power band now.

CSmoney28

Could you post details on the process, turn around time, and cost if you don't mind?

Mr Hammond

It’s been a year this month, but to the best of my recollection, I called them, asked the process, they said just ship the turbo to them with a note inside with info. They’ve built enough at this point where it’s a pretty standard process. 20T billet compressor wheel, high flow 9-blade turbine wheel, and your standard turbo rebuild. Cost at the time was $595 plus $30 shipping. Turn around time is maybe 3-4 weeks? I guess it depends on the season and how busy they are. Just give them a call. Super helpful.

I think Fletcher has a couple already built ones ready to sell, so no down time.

CSmoney28

Oh alright, thanks man appreciate the information.

I've read the whole thread and build, I have most of the mods on your list. I was just wondering if you still have the link to your turbo upgrade for the rdx, your build thread has really helped me build my rdx into a monster btw. Thanks for that also.

EasyLoveRDX

Chiming in as well to say this build thread has helped me immensely. Thanks to all who have shared information.

I just received and installed my ATLP cat back exhaust, which pairs nicely with the K&N Intake I had done a month or so ago. I've also been running Hondata's optimized tune for the RDX, but haven't had any custom tuning done yet.

My one question, that I couldn't seem to figure out from this thread is: If I order an RV-6 hi flow catted downpipe to add to this setup, is it a waste if I don't also upgrade my injectors? Still on the stock 410s, and with just the K&N intake my hondata logs were running about 80% duty at WOT. I haven't datalogged yet with the new exhaust.

I was planning on just the downpipe for my next mod, but I have points and a coupon with Heeltoe, so I'd rather use that to grab both if the injectors and fuel pump are really needed to fully take advantage of the increased flow and power gains from the downpipe.

Mr Hammond

I wouldn’t necessarily call it a waste, but at the same time I wouldn’t install it without tuning and I wouldn’t tune without upgrading the stock injectors so I’d suggest waiting and doing it at once. And if you’re going to do the downpipe, you might as well wait and do the Blouch turbo upgrade too.

You’ve already seen the issues RDXs run into with the stock fueling limits. No need to risk it further. I did mine in two stages: CP-E intake, ETS intercooler, ATLP exhaust, street tuned. Then Blouch turbo upgrade, RV6 downpipe, DW plug and play 800s and a DW 340lph pump, dyno and street tuned.

I’ve since added a J35 throttle body, ported intake, and heat shield gasket, but that was more for building boost off the line than anything else. In hindsight I should have went with 1000s for E85, but the DW 800s were plug and play and that was really appealing without wiring or jumper harnesses. On paper I should be good for around 85% duty on E85 and 400 crank, but that’s not leaving a lot of wiggle room and seeing what these have made on corn, I may run out of fuel before turbo.

Just some things to consider before you commit.

EasyLoveRDX

Actually I'm not familiar with those, could you elaborate or link me a thread?

Also, which heatshield and ported intake did you use?

I did end up datalogging with my current setup, and Flashpro is showing my stock injectors at around 90% duty under WOT. I've heard the stock injectors can safely run near 100% duty, but aftermarket injectors can't, not sure how true this is.

Thanks for your insight.

Mr Hammond

You’re seeing them right now. There’s not a lot of wiggle room in the stock fuel system. Intake, exhaust, and a tune and you’re about at the limits. Adding a downpipe and you’re not going to be able to see the full potential without fuel.

Hondata heat shield gasket, stock intake manifold, but port matched to the J35 throttle body and cleaned up the inlet ports a bit. Nothing fancy. Builds 6-7psi now instead of 2-3psi while foot braking it with the factory safety switch.

There isn’t really a difference between “stock” and “aftermarket” injectors. They’re all made by other companies. Denso makes the “stock” injectors. DW uses a Bosch injector. I wouldn’t trust a tuner that would let you out the door with really anything over about 85% duty cycle on any injector under WOT. Injector failure is a real thing.

FC2012RDX

Anyone know which 1000cc injectors fit? Can't seem to find DW 1000cc injectors and on HeelToe it seems like the 800cc were replaced with 750cc. I wouldn't mind going with the smaller injector but I wanted to leave the door open for possibly doing E85 in the future.

Also, fuel pump would either be the 65C or the 300C.

Any suggestions?

EasyLoveRDX

Follow up to the above post ^ anyone have any experience with the 750cc injectors? There's a note on heeltoe about needing custom splicing on the clips that I don't remember seeing for the 800cc injectors.

Mr Hammond

DW makes 1000cc injectors and at least half a dozen other sizes. Marcus can get them for you. They all fit mechanically, but none of them are plug and play electrically. You’ll either need to get jumper harnesses, splice in adapter harnesses, depin the clips and replace with others etc. Same thing when other K-series platforms want to run the stock RDX injectors: different connectors. The plug and play 800s were a limited run thing.

If you want to run E85, might as well get the 300C. No downside. No price difference. Always good to have room.
